The DOSER™ tracks the use of medication taken from a Metered Dose Inhaler (MDI). This innovative
device provides peace of mind for people with asthma and their caregivers. With its self-contained microcomputer,
the DOSER counts and displays the number of inhalations remaining in the inhaler and displays the number of inhalations
taken in the current day. The DOSER also stores the number of inhalations taken in each of the last 30 days in
its memory and alerts the user when the MDI is nearly empty. With its self-contained battery, the DOSER lasts a
full year. Search and Buy Asthma Books.
